Hi, I'm posting this site that my dear old friend has created. This is done purely as a labor of love and is free to use, no fees no gimmicks, just an easy to use site that can help people who are interested in gaining more knowledge of theory for applications of their own composition. I hope some people find it helpful, Richard, the guy who put it together is a life long musician trained by the Navy and has had some interesting jobs as a musician including playing trombone for the posthumous Glenn Miller band.
